I. LVS (Linux Virtual Server)
LVS is short for Linux Virtual Server. It is a Virtual Server cluster system. LVS operates on the fourth layer of the ISO model because it operates on the fourth layer, therefore, like iptables, it must work in kernel space. Therefore, like iptables, lvs directly wor
In the past, running a large web application meant running a large web server. Because your application attracts a large number of users, you will have to add more memory and processors to your server. Today, the 'large server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs.
The 'more servers' mode has more advantages than the
F5 is a well-known Server Load balancer product. I believe many people will not know it. So how does it maintain sessions? Let's start with the definition of session persistence. As an image metaphor: Session persistence can be seen as a string of pearls, so we split each Pearl and put it in a different box for storage and then put it into a string, that is, the concept of allocation. So how do we describe
: This article mainly introduces how to set up server load balancer with iis in windows. if you are interested in PHP tutorials, refer to it.
Because the project has encountered a large number of image storage problems, although we still have a lot of images (currently up or down 1 TB, it is estimated that the growth rate is 1.3 times per year ), when I think about how to effectively store a large number of

1. Reverse Proxy. When a client request arrives, the reverse proxy receives the request and forwards the request to the backend server. If load balancing is performed, the request is distributed to the Server L
systems or different hardware. For example, a cluster that provides Web Services is a large Web server. However, cluster nodes can also provide services separately.3. Features: based on the existing network structure, Server Load balancer provides a cheap and effective method to expand server bandwidth and increase throughput, enhance network data processing capabilities, and improve network flexibility an

Based on the huge network structure, the use of Cluster Server brings a lot of load problems such as traffic. So the relative, load-balanced technology also emerged. Each technology requires product support, so let's now look at one of the F5 load balancers. So first of all, we first introduce the structure of the product function.Many vendors have launched a
domain name directly resolves to a server (192.168.5.149), by a server load balancer to B server (192.168.5.27) and C server (192.168.5.126).Domain Name resolutionBecause it is not the real environment, the domain name will use a a.com as a test, so a.com resolution can only be set in the Hosts file.Open: C:windowssystem32driversetchostsAdd at the end192.168.5.149 a.comSave exit and then start command mode
